It is about providing.

The present invention provides a variable ultrasonic probe that is integrally equipped with a drive mechanism that changes the incident angle of an ultrasonic beam and a drive mechanism that changes the input direction of the ultrasonic beam, in which the transducer section and the drive mechanism section are connected via gears. However, the vibrator part in the rotor hole and the rotor type vibrator part can be replaced.

In other words, in a variable-angle ultrasonic probe, the transducer section is designed to be easily attached and detached from the drive mechanism section, and the transducer section in the orbiting hole and the rotor-type transducer section are exchanged with each other. It has the functions of both a child type variable angle probe and a rotor type variable angle probe.
